Abstract: PROBLEM TO BE SOLVED: To accurately measure a flow rate by reducing influence of a pulsation flow by providing the first cylindrical parts having the same continuous cross-sectional shape and the second/third cylindrical parts having the tapering inside surface in nozzle members arranged along one of an inflow passage and an outflow passage. SOLUTION: In a flowmeter 10, nozzle members 14 are installed in circular tube-shaped inflow passage 25 and outflow passage 26. The nozzle members 14 have the first cylindrical parts 11 having the same continuous cross-sectional shape and the second/third cylindrical parts 12, 13 having the tapering inside surface connected to the shaft directional downstream side and the upstream side of the cylindrical parts 11. In the nozzle members 14, the cylindrical parts 11 to 13 are formed as a separate body out of rubber having corrosion resistance to gas, elasticity and flexibility. In the flowmeter 10, gas flowing toward the downstream side from the upstream side in the inflow passage 25 and the outflow passage 26 is contracted in a flow by the cylindrical parts 13, and is guided to the cylindrical parts 12 by the cylindrical parts 11.  In this case, the cylindrical parts 13, 12 are formed as the tapering inside surface, a pressure loss is reduced. While, when the gas flows backward to the upstream side form the downstream side, the gas is suddenly contracted in a flow by the cylindrical parts 12, and is guided to the cylindrical parts 13 by the cylindrical parts 11 to be suddenly contracted in a flow.

Title: Heating device
Inventor: YAMAMOTO SHIYUUJI
IPC: H05B3/00
Filed: 1983-05-18
Abstract: PURPOSE:To reduce the temperature change with time during the stable conduction and to stabilize the heating temperature by connecting the control part of a heating element in parallel to the thermostat of a heating apparatus, etc. CONSTITUTION:A heating element 1 is connected in series to a thermostat THS 2, and a series circuit of a diode 3 and a resistor 4 is connected in parallel to the THS2. Then the element 1, the THS2 and the resistor 4 are thermally connected. The voltage of AC full wave is applied to the element 1 while the THS2 is kept on, and the element 1 generates heat to rise the temperature. In this case, no current flows to the diode 3 and the resistor 4 and therefore the operations of these diode and resistor are never effected. When the THS2 reaches its OFF temperature and is turned off, a series circuit is formed among the resistor 4, the diode 3 and the element 1. Then the AC half wave voltage is applied to the element 1, and the heating value is reduced down to half. As a result, the temperature of the heating part is lowered and kept at the saturation temperature of the heating value obtained during application of the AC half wave voltage.

Title: Removal of metal from novolac polymer
Inventor: SUZUKI HIDENORI
IPC: B01J39/18
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To remove metals such as alkali metals and heavy metals from a novolac polymer by passing an organic solvent solution of the polymer through a filter medium on which a zeta potential acts. SOLUTION: The filter medium on which a zeta potential acts is exemplified by a functional filter medium prepared by adding a cationic-charge modifier desirably being a polyamidepolyamine epichlorohydrin cationic resin to a filter medium such as cotton, cellulose, a polyester, active carbon, or zeolite. It is desirable that the thickness of the functional filter medium is 0.01-10 cm and that diameter of the pores of the medium or of the openings formed among particles of the medium is 0.1-1.0 μm. It is desirable to use the filter medium in combination with an ion exchanger and/or a chelate former.  That is to say, the functional medium can adsorb charged particles present in the solution to thereby catch metallic impurities smaller than the pore of the medium by the help of the potential difference generated when the polymer solution is passed therethrough, while the ion exchanger and/or the chelate former can trap free ions in the solution.

Filed: 1987-04-09
Abstract: PURPOSE:To prevent influences of zero-cross signals to a tracking servo system at the time of reproduction, by stopping the operation of a zero-cross detector except a track jumping period. CONSTITUTION:When a track jumping command JP is given to the track jump controlling section 38 of a tracking servo loop 24, a switch 36 is turned on by the control section 38 and the zero-cross of the output of a tracking error signal detecting circuit 26 is detected by a zero-cross detecting circuit 34. The detected zero-cross is counted by the control section 38 and a tracking driver 32 is controlled. Thus a tracking jump is executed. When the detected zero- crosses reach a set number, the switch 36 is turned off by the control section 38 and the operation of the zero-cross detecting circuit 34 is stopped. Therefore, influences of zero-cross signals to the tracking servo system are prevented at the time of reproduction caused by the tracking driver 32 which operates in response to the output of the tracking error signal detector 26.

Title: Masking film
Inventor: TAKAHASHI JUNICHI
IPC: H01L21/306
Filed: 1990-04-02
Abstract: PURPOSE:To obtain a masking film for etching use, which can be formed at a low temperature of room temperatures or thereabouts and by which damage is not inflicted on a circuit on a substrate and the like, by a method wherein the masking film is formed of a carbon film. CONSTITUTION:A carbon film 3 is formed on an Si single crystal substrate 2 by a plasma CVD method. A desired photoresist pattern 4 is formed on this film 3. Then, the film 3 is etched by a dry etching method, in which a plasma reaction is utilized, in a desired pattern so as to remove the carbon film of a part without the photoresist pattern and thereafter, the photoresist pattern is removed by etching or with a release solution. After that, the film 3 is subjected to etching treatment with a KOH aqueous solution. As a result of a measurement of an etching rate using the KOH aqueous solution to a carbon film masking film formed in such a way, an etching rate of roughly the same degree as an etching rate to an Si3N4 film formed by a thermal LPCVD method is obtained. Accordingly, the carbon film is useful as a masking film at the time of a long-time etching. Moreover, as the formation of the masking film can be performed at room temperatures, there is not a rediffusion of an impurity in an active element, which is caused at the time of formation of the Si3N4 film, and the generation of a hillock in an Al film.
